When solving an equation with two variables, replace the variables with the values given and then solve the now variable-free equation. (Remember order of operations, PEMDAS, Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.)
Solve -7b + 4b = -2b - 9y - 8 for b in terms of y.
| \(\frac{1}{6}\)y - \(\frac{5}{18}\) | |
| 2\(\frac{3}{5}\)y + 1\(\frac{3}{5}\) | |
| 7y - 8 | |
| -9\(\frac{1}{2}\)y + 3\(\frac{1}{2}\) |
